Remove comments interpreted as settings

in go-flags/ini_private.go in function readIni there is no mechanism for adding inline comments.  Only comments that have a semicolon as the first non-whitespace character are ignored.  

According to Wikipedia http://en.wikipedia.org/wiki/INI_file#Comments inline comments are not universally supported.  

This change adds some white space for readability, but name := strings.TrimSpace(line[1 : len(line)-1]) removes accidental whitespace left in later.
