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.

Closes #135.
