The sequence "hl" is easy to type but recalling its function after not
using  it a  while  takes  effort.  Seeing  "Hl-Line  mode enabled  in
current buffer" also takes effort to read.

In the spirit of "display-line-numbers-mode" can "highlight-line-mode"
be the full expansion for feedback and the expansion to "hl"?

Steps to reproduce
  . start "emacs -Q"
  . type three lines of "q"
  . on the middle line type "M-x hl" and TAB to use the completion

An improvement from my point of view
  . on the middle line type "hl" and TAB to use the completion
  . the completion expands what was "hl-line-mode" to "highlight-line-mode"

We could consider renaming hl-line-mode to highlight-line-mode, I guess?
Anybody have any opinions?

But I don't think completing hl to highlight-line-mode would make much
sense, even if it was possible, because nobody would be typing `M-x hl
TAB' in the first place without knowing that the mode was called
`hl-line-mode'.

When I have my muddled together emacs configuration not running 
from "emacs -Q" the following shows


  M-x hl
  hl-line-mode
  hi-lock-mode
  holiday-list
  ...

true, I don't use "M-x hl TAB" but "M-x hl C-j" to take the option 
at top of the listing.  I think more sense is gained from

  M-x hl
  highlight-line-mode
  ...

We cannot rename such a veteran mode.  But we can add an alias.

I was thinking of renaming it and adding hl-line-mode as an alias.

On the other hand, there's a gazillion user options and stuff called
`hl-*', so perhaps doing it the other way around makes more sense.

That's okay, of course.

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".
