here's what the regexp page says:
The Simple Regular Expressions described below differ from the
Internationalized Regular Expressions described on the regex(5) manual
page in the following ways:
* only Basic Regular Expressions are supported
* the Internationalization features--character class, equivalence class,
and multi-character collation--are not supported.
if these are indeed the only differences then I can add a REG_NOI18N
regcomp() flag -- but I need verification of exactly what that means
does that mean that it is byte based, or does . match a multibyte char?
