For path that consists of a series of rectangles (shape is 'mlllhmlllh...'), call paint_path again with each group of 5 points. The result is multiple rects instead of a single curve. fixes pdfminer#369

Your code changes look good!
I would like to have some unittests for this, instead of a PDF integration test.
A suggestion: could you add a reference in the docstring of paint_path() to the Section 4.4 of the PDF Reference ("Path Construction and Painting") makes it easier for everyone to understand this method.

Description
For path that consists of a series of rectangles (shape is 'mlllhmlllh...'), call paint_path again with each group of 5 points. The result is multiple rects instead of a single curve.
This fixes #369 which affects PDF generated from Excel and Microsoft Print to PDF. The PDF generated by this method will have borders drawn using a single path instead of multiple rectangles. This allows tables to be drawn as expected when using
pdf2txt -t htmland also when usingpdfplumber(which does not consider rect edges from curves).Fixes #369
How Has This Been Tested?
Added a test case to parse such PDF and inspect the changes by calling
pdf2txt -t html <pdf>before/after the change. Thepdf2txt -t xmlwill also generate<rect>instead of<curve>Checklist
