do_replace_loop(), do_delete(), nano.1, nanorc.5, nano.texi,
and nanorc.sample. (DLR, suggested by Jaime
<re2823@Safe-mail.net>)
+ - Move functions specific to the file browser to their own
+ source file, and adjust related variables accordingly. New
+ file browser.c; changes to striponedir(), browser_init(),
+ do_browser(), and do_browse_from() (all moved to browser.c).
+ (DLR)
- files.c:
read_file()
- Remove apparently unneeded logic to handle a case where
- Tweak the "c-file" regex for characters to properly accept
'\"' and reject '"' and '''. (DLR)
- src/Makefile.am:
- - Add help.c and prompt.c to nano_SOURCES. (DLR)
+ - Add browser.c, help.c, and prompt.c to nano_SOURCES. (DLR)
