Barline at beginning of lines of music.

[Richard Shann]

For chord charts a barline is wanted at the start of each line of music
- \bar "|" is, of course ignored in this position.
Can anyone suggest how to force printing a barline here (after the time
signature, if any).

Incidentally, the documentation is slightly misleading on this point:

http://www.lilypond.org/doc/v2.18/Documentation/notation/bars#index-bar-lines

says

"This and other special bar lines may be inserted manually at any point."
