Subject: ls: --hyperlink: switch to more standard delimiters
X-Git-Tag: v9.10~39
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=dfeb32f6e21cac123f4995bbcbe7e4b4ec81ddb5;p=thirdparty%2Fcoreutils.git

ls: --hyperlink: switch to more standard delimiters

* src/ls.c (quote_name): Use ST (ESC \) rather than BEL,
as that's the only terminator mentioned in at least
ECMA-48, DEC STD 070, and EK-VT520-RM.
* NEWS: Mention the change in behavior.
* tests/ls/hyperlink.sh: Adjust accordingly.

Suggested by Egmont Koblinger.

   'fmt' -w,--width no longer includes '\n' in the width of a line.
   I.e., the specified width is interpreted to be an _inclusive_ maximum.
 
+  'ls --hyperlink' now uses more standard format hyperlinks.
+  'ESC\' (ST) is now used as a delimiter, instead of '\a' (BEL).
+
   'ptx' -t is no longer a no-op, and now sets the default width to 100 columns.
 
   'timeout' now honors ignored signals and will not propagate them.  E.g.,
