splash screen column alignment

splash screen column alignment

Depending on the size of the font I use, alignment of the text in the
*GNU Emacs* buffer (which is done with single tabs) may or may not work
properly.  I’ve found this would be fixed by starting with 2 tabs
separating the columns, and then running:

(align-regexp (point-min) (point-max) "\\(\t\\)[A-Z]")

as part of the construction of the buffer.

I’ve attached some images showing

• the expected behaviour appearing by luck
• the flaw
• the fix (with whitespace mode enabled to highlight the point).

IMO, align-regexp is overkill for this.  We should simply use
:align-to display spec there, which is a core feature that doesn't
need to load any Lisp.

Thanks.
