      , meaning that I cannot use `system()` when creating library function that must be designed to work also with cases like `hg commit -m $'Summary\n\nVerbose description'` (I know that this case may be changed to use `hg commit -l`, but it is not the only case when I use newlines; though all others happen only in shell).
