Subject: Allowed configuration token to start with a variable.
X-Git-Tag: release-1.13.8~5
X-Git-Url: http://www.kaiwu.me/postgresql/commit/static/gitweb.js?a=commitdiff_plain;h=0ad556fe59ad132dc4d34dea9e80f2ff2c3c1314;p=nginx.git

Allowed configuration token to start with a variable.

Specifically, it is now allowed to start with a variable expression with braces:
${name}.  The opening curly bracket in such a token was previously considered
the start of a new block.  Variables located anywhere else in a token worked
fine: foo${name}.
