Bug#1006661: exim4-base: Syntax Error in exiqgrep

[Paul Saunders]

Package: exim4-base
Version: 4.95-4
Severity: normal

Dear Maintainer,

When running /usr/sbin/exiqgrep, a Syntax Error is reported, and the
program quits:

$ /usr/sbin/exiqgrep
syntax error at /usr/sbin/exiqgrep line 56, near ") {"
syntax error at /usr/sbin/exiqgrep line 56, near ";}"
syntax error at /usr/sbin/exiqgrep line 57, near ";}"
syntax error at /usr/sbin/exiqgrep line 58, near ";}"
Execution of /usr/sbin/exiqgrep aborted due to compilation errors.

Looking at the code, the problem appears to be that line 56 is of the
form:

if (!getops(...) { ...}

The unbalanced parentheses are the problem. Adding a second closing
bracket after the getopts call fixes the issue.
