The "1" is a condition, which always evaluates to "true", with no action specified. The default action for a condition, if none is specified, is { print }. So it's shorthand for "print the line".
It's equivalent to:
or just
since an action with no condition is always executed.

RUN-MAILCAP(1) Run Mailcap Programs RUN-MAILCAP(1)NAME
run-mailcap, view, see, edit, compose, print - execute programs via entries in the mailcap file
SYNOPSIS
run-mailcap --action=ACTION [--option[=value]] [MIME-TYPE:[ENCODING:]]FILE [...]
The see, edit, compose and print versions are just aliases that default to the view, edit, compose, and print actions (respectively).
DESCRIPTION
run-mailcap (or any of its aliases) will use the given action to process each mime-type/file in turn. Each file is specified as its mime-
type, its encoding (e.g. compression), and filename together, separated by colons. If the mime-type is omitted, an attempt to determine
the type is made by trying to match the file's extension with those in the mime.types files. If the encoding is omitted, it will also be
determined from the file's extensions. Currently supported encodings are gzip (.gz), bzip (.bz), bzip2 (.bz2), and compress (.Z). A file-
name of "-" can be used to mean "standard input", but then a mime-type must be specified.
Both the user's files (~/.mailcap; ~/.mime.types) and the system files (/etc/mailcap; /etc/mime.types) are searched in turn for informa-
tion.
EXAMPLES
see picture.jpg
print output.ps.gz
compose text/html:index.htm
extract-mail-attachment msg.txt | see image/tiff:gzip:-
OPTIONS
All options are in the form --<opt>=<value>.
--action=<action>
Performs the specified action on the files. Valid actions are view, cat (uses only "copiousoutput" rules and sends output to STD-
OUT) , compose, composetyped, edit and print. If no action is specified, the action will be determined by how the program was
called.
--debug
Turns on extra information to find out what is happening.
--nopager
Ignores any "copiousoutput" directive and sends output to STDOUT.
--norun
Displays the found command without actually executing it.
