Subject: expr: [nfc] remove unnecessary parens and dereference of 'exitf'
X-Git-Tag: 4.0.0~204^2~4
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=ae636e57d1556f9318445433c521b57dda4b0228;p=graphviz

expr: [nfc] remove unnecessary parens and dereference of 'exitf'

The C compiler knows how to dereference and call through a function pointer
without needing this manual instruction.
