ST hangs while opening this file in zsh syntax

[delan]

Description of the bug

Steps to reproduce

1. download and unzip this file: zfs-sync-snapshots.zip
2. subl --safe-mode zfs-sync-snapshots — it hangs at the progress bar
3. rename zfs-sync-snapshots to zfs-sync-snapshots.sh
4. subl --safe-mode zfs-sync-snapshots.sh — it opens normally (but in Bash syntax)

Expected behavior

the file opens normally, even in zsh syntax.

Actual behavior

the file fails to open, hanging permanently at the progress bar, with 100% cpu in “file_read_threa”:

Thank's for reporting. I can reproduce described behavior on Windows as well, using ST4200.

Many fixes have been added to ShellScript syntaxes after ST 4200 was released. One of them seems to fix this issue as well. Provided file loads without issues using latest syntax definitions from https://github.com/sublimehq/Packages/tree/master/ShellScript.
