Previously, `nvm install Argon` would succeed by matching the LTS name
in the version description (e.g., "v4.9.1 (Latest LTS: Argon)"), but
`nvm uninstall Argon` would fail because "Argon" is not a valid alias or not a valid version.
Changes:
- Added pattern matching check in nvm_remote_version (nvm.sh:785-791)
- Skips check for implicit aliases (node, stable, etc.) to preserve
existing functionality
- Added unit tests to verify LTS names are rejected while version
numbers still work
After this fix:
- `nvm install Argon` → fails (use `nvm install lts/argon` instead)
- `nvm install 4` → still works
- `nvm install node` → still works
- `nvm install lts/argon` → still works
This makes install and uninstall behavior consistent.
Fixes#3474.
When `.nvmrc` or alias files contained comments (lines with `#`),
the `#` character could end up in the search pattern passed to sed,
causing "unterminated regular expression" errors because `#` is
used as the sed address delimiter.
This commit fixes the issue in two places:
1. `nvm_alias`: Strip comments from alias file contents before
returning them, and trim trailing whitespace
2. `nvm_ls`: Escape `#` characters in SEARCH_PATTERN so they're
treated as literal characters in the sed address
Fixes#3761
In theory, `npx nvmrc` can now be used to validate an `.nvmrc` file that `nvm` will support. Allowances have been made for future extensibility, and aliases may no longer contain a `#`.
Fixes#3336. Closes#2288.

Path lists in environmental variables often give special meaning to
empty entries (e.g. in PATH or MANPATH). These are represented by
leading or trailing colons, or by doubled colons in the middle of the
list.
Adjust the awk invocation to correctly deal with trailing colons by
printing the separator before every field except the first, and then
printing the final separator that is read from the input - this will
either be a colon or the null string. This preserves leading and
trailing colons in all cases while not adding extra colons in the wrong
place.
Add test to confirm the correct behaviour.
Fixes#3144
