maint1.tex failed to build -- it was the one document that never
regenerated -- because of three source-level LaTeX errors, each masked by
the one before it:
* `gdb program $pid`: a bare `$` opens math mode (meant literally), which
was never closed, so `\endi` hit "Missing $ inserted" / Emergency stop.
Escaped to `\$pid`.
* `{\itshape process_ID}` (x2): a bare `_` is a math-mode subscript in
text. Escaped to `process\_ID`.
* a tabbing block (`\ii ps -C wish` before `\ii gdb ...`, and the
`gdb wish / run / set argc / set argv / source` block) was missing its
`\\` row separators, so multiple `\ii` (= \>\>\>) accumulated in one row
and overran the 4 tab stops -> "Undefined tab position". Added the
missing `\\`.
maint1 now compiles cleanly (two-pass, 0 errors) and `make all` in
doc/latexfiles produces 28/28 PostScript files instead of 27/28.
