[PATCH 1/1] send-email: fix transferencoding config option

[Heinrich Schuchardt <xypron.glpk@gmx.de>]

Since e67a228cd8a ("send-email: automatically determine transfer-encoding")
the value of sendmail.transferencoding is ignored because when parsing
the configuration $target_xfer_encoding is not initial anymore.

Instead of initializing variable $target_xfer_encoding on definition we
have to set it to the default value of 'auto' if is initial after parsing
the configuration files.

The documentation erroneously mentions the option as
sendmail.transferEncoding. Fix that typo.
