The export regexp was only meant to catch values like:
export VARIABLENAME
however after the stricter quoting patch was applied, it was also matching
variables like:
export BAR=foo
and setting the export flag on a variable called "BAR=foo". The = character
is an invalid variable name character. This patch tightens up the regexp
match so it only matches the intended character set and only matches variable
names.
