bug#30393: 24.4; cperl-mode: indentation failure

[paulusm]

### How to foul up indentation in cperl-mode (cperl-indent-command)

# Here is some badly-indented Perl:

          my $sql = "insert into jobs (id, priority) values (1, 2);";
               my $sth = $dbh->prepare($sql) or die "bother";

# try indenting each line above (individually) by pressing TAB
# (cperl-indent-command).
#
# No problem - everything behaving normally.


# Now try this:

          my $sql = "insert into jobs
(id, priority)
values (1, 2);";
               my $sth = $dbh->prepare($sql) or die "bother";

# Note how "my $sth..." doesn't indent properly?  On my system, it
# stays where it is, where I expect it to re-indent to column 0.


# Now anything following refuses to indent:

          print "Help!";


# Comment out the second code block, and the "Help!" line indents
# properly again.

# It's worth noting at this point that the /contents/ of the string
# seem to trigger the issue.  If the "$sql = ..." lines were changed
# to:
#
# first case:
#   $sql = "select * from jobs;";
#
# second case:
#   $sql = "select *
#   from jobs;";
#
# The issue does not appear.
