source_hscroll: Set max_width to sview->cur->file_buf.max_width

[MaskRay]

The old max_width disallows horizontal scrolling when the longest line
can be displayed in one screen. Remove this restriction.

hi @MaskRay . I know it's been ages, however, do you still have an interest in pushing this forward?

Rebased!

(I am using cgdb+rr)

Oh, I see what you want to do here, you want to be able to print the variable under the cursor? (if the cursor could freely move in the source window)

I don't remember the connection between this PR and #141.

But I just checked: currently the key l arbitrary stops scrolling at some column while this PR removes this restriction.

OK. We aren't going to add this behavior into cgdb as is.

Instead, we would attempt to make the source window cursor movable. I'll consider doing this at some point. I'm closing this for now then.
