`GlancesFilter.filter` split the input on every colon and kept only the second
field, so everything after the second colon was discarded:
cmdline:C:/Program Files/.* -> key=cmdline regex=C
name:foo:bar -> key=name regex=foo
The truncation is silent. The leading fragment is usually still a valid regex —
`C` compiles — so the compile guard never fires, the filter matches nothing, and
the process list comes back empty with no error and only a debug log line.
On Windows that is every absolute path, since each one has a drive colon. It
also truncates URLs, IPv6 literals and any `foo:bar` process name.
`split(':', 1)` rather than the repo's `split_esc`: that helper escapes on
backslash and strips the escape characters from its result, which would mangle a
Windows path regex. The separator here needs no escaping — the key never
contains a colon.
