The input files are all generated by various third-party databases and saved as either tab-delimited or comma-separated text files. But, maybe I've been staring at this too long, because I must still be missing something stupid... Example input file, as seen with "less test.txt" in either a Mac OS X terminal or on the Linux console: 
key1{tab}value1{\cM}key2{tab}value2{\cM}key3{tab}value3{\cM}key4{tab}value4
Test Perl script: 
#!/usr/bin/perl -T

use CGI;
my $cgi = new CGI;

my $file = $cgi->upload('file');

print "Content-type: text/plain\n\n";

$file =~ s/(\x0d?\x0a|\x0d)/\n/smg;
while (my $line = <$file>)
{ 
  chop $line;
  ($key, $value) = split(/\t/,$line);
  print "key: $key\nvalue: $value\n";
}
Output: 
key: key1
value: value1{\cM}key2
where {tab} is a tab character and {\cM} is a Control-M character.
