Subject: [PATCH] treewide: fix awk regexp over-escaping
Date: Mon, 29 Apr 2019 22:17:13 -0400
Message-ID: <20190430021713.664490-1-alex_y_xu@yahoo.ca> (raw)

Fix "warning: regexp escape sequence is not a known regexp operator" on
gawk 5.0.0.

Results found by:

- grepping '\\[^\[\\^$.|?*+()a-z]' on *.awk
- grepping 'awk.*\\[^\[\\^$.|?*+()a-z]'
- running awk --lint -f </dev/null >/dev/null on *.awk
