Using external markdown compiler fuses words

[loebl]

When using an external markdown program, some words in the resulting html are concatenated, meaning "some word" becomes "someword". I am using cmark as markdown program.

The bug appears if the markdown compiler does not produce a space at the end of a line.

The fix is easy: in weaver.d append a space on every line read. Patch appended.
