[PATCH v2] Reduce false positive in check-non-portable-shell.pl

From
Torsten Bögershausen <tboegi@web.de>

Message-ID
<201301270847.16646.tboegi@web.de>

check-non-portable-shell.pl is using simple regular expressions to find illegal shell syntax.

Improve the expressions and reduce the chance for false positves:

"sed -i" must be followed by 1..n whitespace and 1 non whitespace "declare" must be followed by 1..n whitespace and 1 non whitespace "echo -n" must be followed by 1..n whitespace and 1 non whitespace "which": catch lines like "if which foo"
