Don't recommend using cperl-hairy

Browse source 
Enabling `cperl-hairy` makes cperl-mode break many Emacs conventions
and can be confusing to new users.  Let's not say that this is the
"recommended mode of use", instead leaving it up to the user.

* lisp/progmodes/cperl-mode.el (cperl-mode): Don't recommend using
`cperl-hairy'.

Setting the variable `cperl-font-lock' to t switches on `font-lock-mode'
\(even with older Emacsen), `cperl-electric-lbrace-space' to t switches
on electric space between $ and {, `cperl-electric-parens-string' is
the string that contains parentheses that should be electric in CPerl
\(see also `cperl-electric-parens-mark' and `cperl-electric-parens'),
setting `cperl-electric-keywords' enables electric expansion of
control structures in CPerl. `cperl-electric-linefeed' governs which
one of two linefeed behavior is preferable. You can enable all these
options simultaneously (recommended mode of use) by setting
`cperl-hairy' to t. In this case you can switch separate options off
by setting them to `null'. Note that one may undo the extra
whitespace inserted by semis and braces in `auto-newline'-mode by
consequent \\[cperl-electric-backspace].
