Consistent format for font-lock-keywords
Add note about pre block syntax highlighting bugs
Don't exclude [^], which is a valid reference tag
More inclusive blockquote regexp
Do not highlight escaped wiki links

Update match group numbers for wiki links accordingly.
Strip properties from returned wiki link names
Generate wiki link filenames generically

Use `markdown-wiki-link-link' so that we generate the
correct filename when alias first mode is either on or off.
Quotation marks should have punctuation syntax

Also, shorten the variable name in the let block.

Inherit from text-mode-syntax-table instead of
standard-syntax-table.
Useful return values for wiki link navigation functions
Add a few example tests using the ert framework
Add inline code tests

Also, write a helper function for checking that an entire range
of characters has a particular face.

The two more complex test cases are known to fail.
Add Makefile with test target
Move all testing-related files to tests/
Provide markdown-test
More specific test suite instructions
More representative inline code edge cases
Add Makefile rules for producing html for test cases
More accurate inline code regexp

No need to prohibit spaces after the leading backquotes.

Markdown.pl allows more than two leading backquotes (but
the same number must appear at the end to close the code
tag).
