Something I do quite often is linking to PHP documentation pages. PHP has nice URL rewriting, so you can simply write this to link to the documentation of a function:
Something that happens quite often to me, is that I forget the write out the host:
This breaks the link, causing the answer to be broken and forcing me to fix it in an edit.
I think that it is worth patching markdown to allow such URLs, letting it assume the
http protocol. It should be a trivial change, but would make typing URLs simpler and prevent at least some broken URLs.
So, what do you think? Does this happen to you, too? Or is this only something unique to me and thus not worth changing?
