How to handle "\" indicating next line

[Khairul Azmi]

Hi all,
I am writing a code that would check line by line content of a line before
processing it. Problem occurs when there are lines that has character "\"
indicating a new line. For example

preprocessor http_inspect: global \
    iis_unicode_map unicode.map 1252

When that happen, my code should be able to grab the whole phrase. My
current code would only capture up to "global \". Thanks in advance.

if (open (INFILE,"$snort_file")) {

    while (<INFILE>) {
    my $line = $_;
    if ($line !~ /^[[:space:]]*#.*$/) { # handle lines start with #
        if (/\S/) {                     # handle empty lines
        my @field = split;

        } elsif ($field[0] eq "preprocessor") {
            get_preprocessor ($line);
       }
