Controlling the Prompt with not-printable sequences.

[drm343]

My bash prompt work incorrect when use shml.
If prompt line too long, then text will overwrite the screen of current line and hard to see.

This bug appear because non-printable sequences. I fix this after add "\[" and "\]" in fgcolor and bgcolor.
