Subject: [EXPAND] Fix quoted pattern patch breakage
X-Git-Url: http://git.kernel.org/?p=utils%2Fdash%2Fdash.git;a=commitdiff_plain;h=0d7d66039b614b642c775432fd64aa8c11f9a64d

[EXPAND] Fix quoted pattern patch breakage

The change

[EXPAND] Do not quote back slashes in parameter expansions outside quotes

broke quote removal after parameter expansion.  This is because
its effecte extended beyond that of quoted patterns.

This patch fixes this by limiting the change to just quoted
patterns.
