[ISSUE] Need a way to insert a CodeSnippet coming from a .sh file

[lestephane]

I'd like to insert a code snippet that comes from a .sh file.
This would require some escape sequence that starts with #.

.sh file

#Showcase start maxCodeSize
readonly local max_code_size_kb=$(bc <<<"1024 * 1.5 / 1")
#Showcase end maxCodeSize

markdown

- It has a code size of less than 1.5 M ([source](itests/src/test/scripts/jar-tests.sh))
