The man page (crontab(5)) says:
An active line in a crontab will be either an environment setting or a
cron command. An environment setting is of the form,
name = value
where the spaces around the equal-sign (=) are optional, and any subse‐
quent non-leading spaces in value will be part of the value assigned to
name. The value string may be placed in quotes (single or double, but
matching) to preserve leading or trailing blanks.
Assuming that it uses shell syntax would be a mistake. If you need
some of the parameters to be processed by a shell, put them in the cron
command line, or in the script that the cron command calls.
