* Add goland IDE prefs to .gitignore
* Add flag for removing leading H1 heading in markdown; fixes#35
* Remove manpage reference to unused -n and -c args
* Add manpage docs for --drop-h1 argument
* Update docs; add docs for --drop-h1 argument
* Rename method to be more verbose; add code comments
Renames to `DropDocumentLeadingH1` to better denote the method's
purpose and adds code docs to this effect in order to hopefully
negate potential misuse on single lines.
* Revert "Add manpage docs for --drop-h1 argument"
This reverts commit 48a641baed05540f6172fe9b780b06eacad4dc28.
The `--drop-h1` flag is not understood as an argument in this
context, but rather is folded under `[options]`. This change
caused the arguments to not be properly parsed when the --drop-h1
flag was passed.
