Subject: bug#11263: 23.4; shell-script: << does not always mean here-document
Date: Tue, 17 Apr 2012 12:24:00 +0200 [thread overview]
Message-ID: <87r4vmy7un.fsf@ypig.lip.ens-lyon.fr> (raw)
When I type << in shell-script mode, Emacs thinks this begins a
here-document. This is not always the case, e.g. in the following
lines:
foo='bar<<'
echo "${foo%<<}"
echo $((1<<8))
And specifically for zsh:
echo $[1<<8]
