Fix ls-files quoting

[quozl]

File names are quoted and then mishandled by the builder.
http://lists.sugarlabs.org/archive/sugar-devel/2021-February/058971.html

Use null-terminated files.

Untested.

Tested, goes into an infinite loop with error;

Looking more into it.

Took a look and I'm yet to figure out why it goes into an infinite loop even when ignore is True.

Looked into it, but could not reproduce your problem easily. Used sugarlabs/flipsticks@eb48ca9.

Paths in traceback show local bundlebuilder is used. Check.

Applied my patch, and a CPU loop occurs for a while then RecursionError.

It would appear the coding is not defensive. 😁

Pushed a fix.

[chimosky]

Tested, works as expected. Thanks.
