Kurtis Rader	0ca103686f	remove unset vars from the environment ... Remove vars from the environment that are no longer set. Simplify the code by removing an unnecessary loop. Add some tests. Fixes #3124	2016-06-15 22:10:11 -07:00
Kurtis Rader	c2f1df1d4a	fix handling of non-ASCII chars in C locale ... The relevant standards allow the mbtowc/mbrtowc functions to reject non-ASCII characters (i.e., chars with the high bit set) when the locale is C or POSIX. The BSD libraries (e.g., on OS X) don't do this but the GNU libraries (e.g., on Linux) do. Like most programs we need the C/POSIX locales to allow arbitrary bytes. So explicitly check if we're in a single-byte locale (which would also include ISO-8859 variants) and simply pass-thru the chars without encoding or decoding. Fixes #2802.	2016-03-20 18:47:38 -07:00
