Message:

Give owl_text_indent an indent_first_line parameter

This is useful if you need to indent text that isn't broken into chunks
that end with newlines.

This is primarily in preparation for the next commit, where we need to
replace the indent on the first line by a prefix.  The other
(reasonable) option is to make owl_text_indent always prefix the string
it's given with an indent, even when it's given the empty string.  This
would break the nice property that indent(A + B) = indent(A) + indent(B)
whenever A ended with a newline.  After some discussion on zephyr and on
the github pull request, I decided to go with this option.
