[bash] issue while escaping quote

[braoult]

• Prism version: 1.19
• Environment: Firefox 74.0, XUbuntu 19.10.

Prism looks "lost" with Bash code having this syntax :

printf -v aval "%d" \'a                   # 'a' ascii value
printf -v zval "%d" \'z                   # 'z' ascii value

It looks like it considers the first quote in comment to be the end of a string, the string start being the escaped quote. What is most disturbing is that all lines following these lines are wrongly colorized, as we can see on:
https://exercism.io/my/solutions/7a25d82ea512403280f7fd168040eefb?iteration_idx=1, where colors are all wrong after line 56.

Workaround 1: The following works with prism (no single quote in comment) :

printf -v aval "%d" \'a                  # "a" ascii value
printf -v zval "%d" \'z                  # "z" ascii value

Workaround 2: using double quotes instead of escaping with backslash :

printf -v aval "%d" "'a"                # 'a' ascii value
printf -v zval "%d" "'z"                # 'z' ascii value
