Subject: parser: Use yyless(0) instead of unput(*yytext)
X-Git-Tag: 0.9.28~1285^2~709
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=04b6be48fa2b4dfd958eebe90687cd754b1ac1a0;p=pakfire.git

parser: Use yyless(0) instead of unput(*yytext)

unput fails for the first character in the body that is being scanned
and yyless is more efficient than unput, too.
