Changes between v5.6.1 and v5.7:

---

Benno Schulenberg (62):

• build: drop the check for two functions that we don't use any more
• build: fix compilation for --enable-tiny plus --enable-multibuffer
• build: fix compilation when configured with --disable-multibuffer
• build: fix compilation when configured with --enable-tiny
• bump version numbers and add a news item for the 5.7 release
• chars: implement mblen() ourselves, for efficiency
• chars: implement mbtowc() ourselves, for more efficiency
• chars: work around a UTF-8 bug in glibc, to display invalid codes right
• chars: work around the wrong private-use-character widths on OpenBSD
• display: avoid determining twice from and until where to draw each row
• display: make the output of --constantshow less jittery
• editing: prevent the pointer for the top row from becoming dangling
• feedback: upon first switch to a buffer, show its error message (if any)
• files: always register the format, also when the file is unwritable
• files: create a new buffer earlier, so that error messages can be stored
• files: when Mac format has been detected, stay with it
• gnulib: pull in the fix for a build problem on older Debian
• gnulib: update to its current upstream state
• indicator: adjust the size to the number of visible lines, not chunks
• input: accept Unicode codes for non-characters as valid, since they are
• memory: do not allocate space for multidata when it's already allocated
• memory: fix an off-by-one error to free also the last line in a group
• memory: prevent a use-after-free when the user respects a lock file
• oops: that doesn't work -- you can't break out of two for loops at once
• options: retire the obsolete 'smooth', 'morespace', and 'nopauses'
• softwrap: avoid time-consuming computations, to burden large files less
• startup: do not crash when trying to open a device or directory
• startup: do not store an error message in the record of another buffer
• startup: save the compiled file-matching regexes, to avoid recompiling
• startup: show the helpful message only when ^{G has not been rebound}
• syntax: c: colorize also labels that contain digits, and uncolorize colon
• syntax: po: improve the coloring of format specifiers
• syntaxes: replace :space: with :blank: to exclude carriage return
• tweaks: adjust and improve one comment, and frob another
• tweaks: adjust two comments, and reshuffle two fragments
• tweaks: avoid a warning on newer compilers, by writing an extra byte
• tweaks: avoid calling extra_chunks_in() when not softwrapping
• tweaks: avoid converting a file name for more than will fit on screen
• tweaks: avoid parsing a multibyte character twice
• tweaks: condense three comments, drop another, and rewrap a line
• tweaks: drop unneeded braces and adjust indentation after previous change
• tweaks: elide a call of strlen() for every row
• tweaks: elide a function that is now basically just two lines
• tweaks: elide an unneeded resetting NULL call to wctomb()
• tweaks: elide a small function that is used just once
• tweaks: elide the pointless is_valid_unicode() function
• tweaks: elide two more instances of useless character copying
• tweaks: improve a couple of comments
• tweaks: morph a function into what it is actually used for
• tweaks: normalize the indentation after an earlier change
• tweaks: put the most likely condition first, for a quicker return
• tweaks: reduce the maximum character length from six bytes to four
• tweaks: remove a misplaced (and nested) #ifdef
• tweaks: rename a variable, away from an abbreviation
• tweaks: rename a variable, for contrast with another
• tweaks: reshuffle a comment, and put the main extension first
• tweaks: reshuffle a fragment of code, to prepare for the next change
• tweaks: reshuffle two conditions, to have the most unlikely one first
• tweaks: set the file format only when unset, so it doesn't need saving
• tweaks: shorten a comment and trim an #ifdef
• tweaks: simplify two fragments of code
• tweaks: simplify two fragments of code, eliding useless character copying

Hussam al-Homsi (1):

• syntax: c: make the highlighting of '#include <...>' more compliant

Mike Frysinger (1):

• syntax: tcl: support Expect scripts too
