Subject: fix the treatment of the parameter-based precision, as in "%.*s%s" as
X-Git-Tag: upstream/7.37.1~8398
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=2f928797cf18d41d4ae0114958cfedac3fcd6c13;p=platform%2Fupstream%2Fcurl.git

fix the treatment of the parameter-based precision, as in "%.*s%s" as
previously the second %s would wrongly get the numerical argument that is used
for the variable precision for the first %s...
