This commit aligns the shebang highlighting in bash syntax to what the
Linux kernel will recognise as a valid shebang construct.
In summary, the kernel will accept both headers:
#!/usr/bin/env lua
#! /usr/bin/env lua
The second one is quite prominently used throughout documentation
online, such as on Wikipedia's page for Shebang (Unix) [1].
Some sources are adamant it wouldn't be supported at a kernel level, but
it looks to me, upon closer inspection of the current kernel code [2],
that it is indeed quite evidently valid. It'll simply skip over to the
first character that's neither a space 0x20 nor a tab 0x09.
