I'm not sure if the problem I'm seeing is an artifact of sed or simply a beginner's mistake. Here's the problem: I want to add a zero-width space following each underscore between XML tags. For example, if I had the following xml:

devel::leak
Leak(3) User Contributed Perl Documentation Leak(3)NAME
Devel::Leak - Utility for looking for perl objects that are not reclaimed.
SYNOPSIS
use Devel::Leak;
... setup code
my $count = Devel::Leak::NoteSV($handle);
... code that may leak
Devel::Leak::CheckSV($handle);
DESCRIPTION
Devel::Leak has two functions "NoteSV" and "CheckSV".
"NoteSV" walks the perl internal table of allocated SVs (scalar values) - (which actually contains arrays and hashes too), and records
their addresses in a table. It returns a count of these "things", and stores a pointer to the table (which is obtained from the heap using
malloc()) in its argument.
"CheckSV" is passed argument which holds a pointer to a table created by "NoteSV". It re-walks the perl-internals and calls sv_dump() for
any "things" which did not exist when "NoteSV" was called. It returns a count of the number of "things" now allocated.
CAVEATS
Note that you need a perl built with -DDEBUGGING for sv_dump() to print anything, but counts are valid in any perl.
If new "things" have been created, "CheckSV" may (also) report additional "things" which are allocated by the sv_dump() code.
HISTORY
This little utility module was part of Tk until the variable renaming in perl5.005 made it clear that Tk had no business knowing this much
about the perl internals.
