bug#8077: cperl mode - indenting after long attribute list

[Ronald J Kimball]

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

Create a new file in cperl-mode.
Enter the following line:
sub foo : a('a') abcdefghi('foo') jklmnop('bar') qrstuv('baz')
On the next line, press tab.
Bug: It takes a long time for the indent to happen.
Make any attribute name longer, and the time increases considerably.

I can reproduce this on current master.
