Subject: When providing a block literal as a code completion for a
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=c2760bc8e99510c4b3848fcd21323afd711ee269;p=clang

When providing a block literal as a code completion for a
function/method argument, include the parameter name and always
include parentheses (even for zero-parameter blocks). Otherwise, the
block literal placeholder '^' can look very weird.
