Subject: tc/lexer: let quotes actually start strings
X-Git-Tag: v4.15.0~3
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7ac29190dbbc03ee2e60406ba8c584ac3c18c6c9;p=thirdparty%2Fiproute2.git

tc/lexer: let quotes actually start strings

The lexer will go with the longest match, so previously
the starting double quotes of a string would be swallowed by
the [^ \t\r\n()]+ pattern leaving the user no way to
actually use strings with escape sequences.
Fix this by not allowing this case to start with double
quotes.
