heredoc_unindent 1.0.1

Removes common margin from indented strings such as the ones produced by heredocs, i.e., strips out leading whitespace chars at the beggining of each line (but only as much as the line with the smallest margin). It is acknowledged that many strings defined in heredocs contain nothing but code to be read exclusively by parsers (e.g., Kernel#eval or web browser's), which are basically insensitive to extra indentation. Nevertheless, in cases when the string is printed or displayed, the unintended indentation is rarely innocuous -- and thus the reason for this gem.
