Also, with emacs  customized the way that works for  me, the following
happens to "M-x hl TAB"

  M-x hl TAB
  [listing changes unexpectedly]
  M-x h-l
  flush-lines
  LaTeX-math-lg
  LaTeX-math-ll
  ...

What triggered me to file this bug is this chicken and egg problem.

I want to  activate "highlight line" mode but my  short term memory at
the finger  tips has  forgotten "hl"  at the  "M-x hl  C-j".  So  I go
typing "M-x  highlight" but  the generated  listing doesn't  fetch the
unavailable  "hl-line-mode"  which  I  very  much  prefer  to  see  as
"highlight-line-mode".
