When `org-edit-src-content-indentation’ is non-nil (default: 2), editing SRC blocks preserves this amount of extra indentation space at the beginning of each line of the block, removing and then re-adding it on round trips through `org-edit-src-code’.
But `org-src-font-lock-fontify-block' does not consider this extra space. Instead it simply copies the full block verbatim into e.g. *org-src-fontification:python-mode*, as if the extra indent space were a legitimate part of the source. Normally this wouldn’t be a problem, as faces are attached to keywords. But for any fontification that depends explicitly on indentation, this leads to incorrect results. For example, my indent-bars package adds indentation bars via text properties based on absolute column position. These bars are then offset in the displayed org src block by 2 columns from their correct locations, due to the extra space org has put there.
A sensible solution might be for fontify-block to strip `org-edit-src-content-indentation’ worth of space from the beginning of each line, just as is done for src block editing, then perform the fontification, then add that space back to the fontified text for display.
Thanks for all your work on org.
