Subject: git-prompt: use here-doc instead of here-string
X-Git-Tag: v2.47.0-rc0~86^2~7
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=f037e607a875790dcadbba3f7a8fc185e2877792;p=thirdparty%2Fgit.git

git-prompt: use here-doc instead of here-string

Here-documend is standard, and works in all shells.

Both here-string and here-doc add final newline, which is important
in this case, because $output is without final newline, but we do
want "read" to succeed on the last line as well.

Shells which support here-string:
- bash, zsh, mksh, ksh93, yash (non-posix-mode).

shells which don't, and got fixed:
- ash-derivatives (dash, free/net bsd sh, busybox-ash).
- pdksh, openbsd sh.
- All Schily Bourne shell variants.
