I think perhaps this is an unintended side effect.
If I create an Fl_Input and make it much larger than
a single line, and set wrap(1), it does indeed 'wrap'
if I type enough to hit the right edge, and it moves
to the next line (even though it's one continuous line),
but there's a bunch of dead white space at the top
(it seems the text is centered) and when you go off
the bottom of the widget, the cursor disappears where
it can't be seen.
This could probably be modified so that if the widget
is larger vertically than a single line, it could disable
the text centering, so that it hugs the upper left
(the way Fl_Multiline_Input does). Then perhaps this
could be a 'supported' feature.
But you're still screwed if the input fills the entire
widget; in Fl_Input mode, the cursor goes off the bottom,
and you can't scroll to it with the up/down arrows or page
keys (since it's all one line).
I myself have had the rare need for a "single line input"
field that word wrapped. (Example: a prompt for a one line
unix command, where the line might be very long)
In my case I made a custom widget from Fl_Text_Input
that enabled wrap, and prevented the user from typing Enter,
and a modify callback to prevent copy/pasting a crlf'ed line.
This way scrollbars would appear if the line went off the
bottom of the widget (which is why I didn't use Fl_Input
and Fl_Multiline_Input, because they don't support scroll bars)
