Leading tabs in code block are not retained in org reader with -p #10071
Description
Explain the problem.
I tried to convert an org-mode file to Markdown. When using pandoc with -p option to preserve the tabs in the Makefile source block, I found the leading tab is converted to single space while the other tabs remain unexpanded.
Minimal example
$ cat example.org
#+begin_src makefile
%.o: %.cpp
$(CXX) -o $@ $<
#+end_srcThere is a leading tab and tabs between entries in the directive. When converted to markdown with and without -p
$ pandoc -f org -t json -p example.org
{"pandoc-api-version":[1,23,1],"meta":{},"blocks":[{"t":"CodeBlock","c":[["",["makefile"],[]],"%.o: %.cpp\n $(CXX)\t-o\t$@\t$<\n"]}]}
$ pandoc -f org -t json example.org
{"pandoc-api-version":[1,23,1],"meta":{},"blocks":[{"t":"CodeBlock","c":[["",["makefile"],[]],"%.o: %.cpp\n $(CXX) -o $@ $<\n"]}]}On the other hand, the markdown reader seems fine (I don't know how to make markdown block within a code block correctly rendered, so I added a comma before backticks)
$ cat example.md
,```makefile
%.o: %.cpp
$(CXX) -o $@ $<
,```
$ pandoc -f markdown -t json -p example.md
{"pandoc-api-version":[1,23,1],"meta":{},"blocks":[{"t":"CodeBlock","c":[["",["makefile"],[]],"%.o: %.cpp\n\t$(CXX)\t-o\t$@\t$<"]}]}
$ pandoc -f markdown -t json example.md
{"pandoc-api-version":[1,23,1],"meta":{},"blocks":[{"t":"CodeBlock","c":[["",["makefile"],[]],"%.o: %.cpp\n $(CXX) -o $@ $<"]}]}Expected behavior
$ pandoc -f org -t json -p example.org
{"pandoc-api-version":[1,23,1],"meta":{},"blocks":[{"t":"CodeBlock","c":[["",["makefile"],[]],"%.o: %.cpp\n\t$(CXX)\t-o\t$@\t$<\n"]}]}Pandoc version?
