Addressed harmless design-bug with output of the --prependPathRel option

The option --prependPathRel should never have printed "./" at the head of any line of output. It's redundant, clutters up the output, and doesn't add any helpful information. However the presence of "./" in a line of output up until this release was totally harmless apart from aesthetic considerations.

Therefor this is a design-bug fix, and with this fix lsseq -R -P and lsseq -R -P * (i.e. with the globbing wildcard) NOW produce the exact same results in any given directory from which lsseq is run.

Stripping "./" from the head of the relative path will not break any scripts that might be using this option, because the path with or without "./" refers to the exact same set of files.
