This is wrong. "vis -l" outputs \$, and with this change, unvis won't
correctly handle it.
unvis is not intended to reverse shell-style escapes. You can use
the shell's eval command for that.
Doesn't eval kind of defeat the purpose of shell sanitisation which
VIS_SHELL is supposed to achieve?
I can always add $ to "the don't encode this" list for VIS_CSTYLE.
