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"
